Interesting, can you cure my ignorance on why they don't claim to include 5.5.13 kernel in the main download page? I'm not super familiar with how distros are packaged up for consumers
Is the main download page the rough equivalent to `master`, and your link is like the feature branch for merging the latest kernel version into the distro?
The download page is for the monthly generated install isos, during the install process it will sync with repos and install the latest version
I would guess that we'll get 5.6 in the coming days.
